soon:
- BerliOS Bug #11576, thread on fetchmail users "Invalid SSL certificate" by
  Philip Susi, SSL negotiation does not use ERR_error_string(3ssl) to report
  errors in a readable way, we just report socket errors with no good reason.
- find a solution for the "invalid header" discards message problem
  (escape headers and stuff reminder into body)
- https://bugzilla.novell.com/show_bug.cgi?id=246829 - fetchmail lost some mail
  (5XX error code in contradiction with manual?)
- http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=432618
  * write a table of combinations of TLS/SSL options
- add To: header to warning mails (authfail for instance)
- add Message-ID: header and other SHOULD headers to warning mails?
- BerliOS Bug #11797, imap_mark_seen doesn't consider expunged messages
- BerliOS Bug #10972, Fetchmail refetches big messages repeatedly (SMTP listener
  issue)
- report multiline SMTP errors properly (sample in private mail from 
  Earl Chew, 2007-07-30T02:28)
- publish SA-2007-02 after release
- Debian Bug#449179, smbutil.c:90: unicodeToString: Assertion `len+1 < sizeof
  buf' failed, from Stepan Golosunov <stepan@golosunov.pp.ru>
questionable:
- fetch IMAP message in one go (fetchmail-devel by Adam Simpkins
  <simpkins@cisco.com> around Nov 2nd)?

6.4:
- change SSL/TLS UI incompatibly, making it easier to use
- allow selection of SSL/TLS Ciphers
- perhaps switch to libgsasl and libgnutls (which doesn't talk SSLv2)
- make the SSL default v3 (rather than v23).
- put more hints to the FAQ (should we call it FGA?) as first support place
- make sure we print socket error messages such as connection reset by
  peer to hint users the problem is not in fetchmail
- > b) When the envelope header is specified, but it isn't found, a
  > warning is logged and the mail is forwarded to the postmaster
  > ("WARNING: Envelope header $HEADER found, cannot identify the
  > recipient.  Forwarding to the postmaster")
  Rob MacGregor 2007-03-16 Patch to the man page, fetchmail-devel@
- integrate Isaac Wilcox's test rig
- look at Tony Earnshaw's .spec file
- look at Gentoo patches
- remove dead replacement functions: strdup (Andreas Krennmair), ...
- more SMTP/LMTP error detail on message rejections even outside verbose mode.
  Ian D. Allen, fetchmail-users. Two messages with examples.
  What goes here? fetchmailrc location, server, port, user, folder, anything else?
- see if "AUTH SSH" can be made to work for POP3
- revisit BerliOS patches
- check recent list mail
- check Debian BTS and other bug trackers
- better logging (log all headers, log forward destination + method)
- check strict envelope N Received parsing,
  see mail from Admin Att on fetchmail-users
- 6.3.4-pending-deletes.patch
- fetchmail -s with running daemon complains rather than silently
  restarting daemon
- send warning message when connection fails?
- when logging to syslog, disable locale?
- check FAQ O5 - do we really prefer From: over envelope?!?
- add code to allow safe authentication schemes if TLS fails
- make APOP an authenticator, integrate with regular auto authentication
  but stuff it at the end
- use SASL?

DOCUMENTATION:
- Add info whether Keywords are global, server or user keywords
- consolidate multidrop documentation
